ELECTRIC DISTRIBUTOR FOR SEAL-ING- WAX.

Application filed December 23,1920. Serial No. $2,772.

resident of 24: Rue Francois l-er, Paris,

France, a citizen of the French Republic, have invented certain new and useful Improvements in an Electric Distributor for Sealing Wax, of which the following is a specification.

The present invention has for its subject an electric distributor for sealing wax principally comprising, a small crucible in the walls of which is enclosed an electric resistance and in the interior oi which sticks of sealing wax are placed, a plunger for regulating the outlet orifice at the lower end of the crucible, this plunger being operated by any suitable means through the medium of a system of levers supported at the upper end of the crucible, and finally at the top a casing preferably constructed of a material which is a bad heat conductor. By means of this apparatus it is possible to control at will the necessary quanity of wax for sealing purposes, thus ensuring the regularity in the formation of the seal and preventing any loss or waste of sealing'wax.

Moreover the casing providedat the up per end of the crucible cools the upper portion of the used mass of wax and prevents if from boiling and flowing over.

In the accompanying drawings is illustrated a section of one form of construction according to the invention.

As will'be seen from the drawing the apparatus comprises a double-walled conical crucible 1, a suitable resistance adapted to be disposed between the double-walls and connected to a flexible wire 2 passing through the handle 3 of the apparatus and secured to a suitable socket member for attaching to a source of current such. as the light mains.

At the upper end of the crucible and on a screwed portion thereof is screwed a'member 4: preferably constructed of a material which is a poor conductor of heat. If this member were omitted the fused wax on boiling would flow over and down the sides of the crucible on to the object to be sealed. By using this member 4, however, a cold zone is provided for the fused sealing wax, which cools the upper portion of the mass of wax and prevents it from overflowing. In the interior of the crucible, a plunger 5 is mounted on a lever 6, the plunger being adapted to cooperate with a conical orifice formed at 7 at the lower end of the crucible. According to the position of. the plunger 6,-the passage area for the fused sealingwax maybe made larger or smaller and if desired maybe closed completely. The "lever 6 is hinged to one end of a small bell-crank lever 8 which is pivotally mounted in a h1g9 secured to the member 4-. Theother end of the lever 8 is connected by a connecting rod 10 to a spring 11 secured to the handle 3 of the apparatus. normally to close the outlet passage for the sealing wax which, the operator can open.

to the required extent when holding the handle 3 by pressing more or less tightly upon the spring.

At the point of connection of the lead 2 t0 the electric resistance in the walls of the crucible, any suitable controlling device 12 may beprovided which can be operated from the exterior. This controlling device permits of regulating the quanity of electricity supplied to the resistance in accordance with the nature and consistency of the sealing wax employed.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is l. A device for applying sealing wqax' comprising a-crucible for the reception of sealing wax, electric means for heating said crucible, and means at the upper end of said crucible for cooling the fused sealing wax rising to the top of the crucible and thus preventing the overflow thereof.

2A. device for applying sealing wax comprising a crucible for the reception of The spring 11 is adapted,

sealing wax, electric means for heating said crucible, and means constructed of poor heat conducting material mounted at the upper end of said crucible and forming an upward extension thereof.

3. A. device tor applying sealing wax comprising a double-walled crucible for the reception of sealing wax, said crucible having an outflow orifice at its lower end,

an electric resistance contained between the double walls of said crucible, leads connected to said resistance, a member of poor heat conducting material mounted at the upper end of said crucible and forming an upward extension thereof, and means for controlling the passage area of the outflow' orifice.

4:. A device for applying sealing wax comprising a double walled conical crucible for the reception of the sealing wax, said comprising a double-walled crucible for the reception of sealing wax, said crucible having an outflow orifice at its lower end, an electric resistance contained between the double walls oi? said crucible, leads connected to said resistance, a current controlling device between one of the leads and the electric resistance, a member of poor heat conducting material mounted at the upper end of said crucible and forming an upward eX- tension thereof, and means for controlling the passage area of the outflow orifice.
